i made new topic issue. kim told\ anonymous requests typically means not find username/password not token in clients request. remember token on first request should reused subsequent requests client code (all kbmmwsimpleclient, kbmmwclientquery, kbmmwclientresolver etc). on way centralize put tkbmmwsimpleclient on datamodule , specify client query components use simple client instance template. first thing before else in client application, make initial "login" request call via simpleclient. i changed serversidequeryallclick on client app. copied token server side client edit1.text. procedure tform1.btnnamedserversidequeryallclick(sender: tobject); begin // gets records server event table. if length(trim(edit1.text)) > 0 begin kbmmwsimpleclient1.disconnect; kbmmwsimpleclient1.username:= cb1.text; // login -> franz kbmmwsimpleclient1.password:= cb2.text; // password -> franzpassword ...

i trying use qsort on array of structs error: expected primary-expression before '*' token struct muchie { int x,y,c; } a[100]; int cmp(const void* p, const void* q) { muchie vp,vq; vp=*(muchie* p); vq=*(muchie* q); return vp.c-vq.c; } // .... qsort(a,m,sizeof(muchie),cmp); the casting of parameters wrong - should *(muchie*)p instead of *(muchie* p) . use: int cmp(const void* p, const void* q) { muchie vp,vq; vp=*(muchie*) p; vq=*(muchie*) q; return vp.c-vq.c; }

i have these 2 tables: table p | b --------- x | 2 x | 7 x | 10 x | 28 y | 24 mapping m c | d ----------- 7 | 2136 28 | 786 24 | 4212 124 | 5311 935 | 6012 if can find matching value of column b in table p value in column c of mapping m, need add value of column d table p well. for example, 1st record of x , 2 of table p, can't find 2 in column c of mapping m, nothing added. 2nd record x , 7, can find 7 in column c, gonna add x , 2136 table p. hence added table p: x | 2136 x | 786 y | 4212 i find challenging insert these 3 rows. i can this: select p.*, m.d @tablep p join @mappingtable m on (p.b = m.c) and put result temp table , insert, how do in 1 insert statement? i realized it's quite straightforward: insert @tablep select p.a, m.d @tablep p join @mappingtable m on (p.b = m.c)

i have folder called "raw" in res folder selection of short audio tracks , screen displays several buttons. i able start mediaplayer this... string[] track = {"track1", "track2", "track3", etc...} mplayer = mediaplayer.create(this, r.raw.track[x]); the issue r.raw.track[x] . is there way in way i'm attempting or need whole new approach? thanks in advance advice can offer. i going assume here x index, perhaps pulled user selection track . you have 2 main options: have corresponding int[] {r.raw.track1, r.raw.track2, ...} , r.raw value way use getresources().getidentifier() identifier @ runtime the second option easier uses reflection , not super-quick. in case, should not matter, doubt looking these ids in tight loop.

this question has answer here: how remove elements @ set of indices in vector in matlab? 1 answer in r, can following: v <- 11:20 v[-(4:5)] and 11 12 13 16 17 18 19 20 , indices except 4th , 5th. is there equivalent in matlab's indexing logic? however wrap mind around it, not seem correct search terms google own result elementary question. note: of course might use of set functions, e.g. v = 11:20; v(setdiff(1:length(v), 4:5)) however, not intuitive. an alternative remove elements array: u = v; u(4:5) = []; i'm using temporary variable since don't know if it's acceptable modify original array v or not.

suppose have web application ebook shopping, users can download books have paid. , ebooks data(like epub data) stored in s3, users got s3 download url when our app validated user bought 1 book. i know s3 generate temporary , time-limited urls user. problem url temporary , time-limited, happen if chance user temporary url within limited time? ok 1 way seems letting limited-time short, 10 seconds, potential risks still there. i know question rigorous, how deal it? or forget it? if concern buyer distribute url, equally distribute file they've downloaded. if concern hold of url without buyer's knowledge, perhaps protect download token buyer know (e.g. password of sort). make url unusable other buyer. downside inconvenience people who've paid product.
